Georgia [21]

Answer:

So, cows heart best is faster than horse.

Step-by-step explanation:

Time and heartbeats are in direct proportion.

   p = kx

Where p is the beats per minute and x represents time in minutes

Now, to find the value of k, substitute p = 152 and x = 4

152 = 4k

  k = 152/4

  k = 38

\sf \boxed{p = 38x}

Cow:  y = 65x

So, cows heart best is faster than horse

Total = 16 marbles
R = 4
B = 7
G = 5

a)
P(R) = 4/17
with replacing it P(B) =  7/17
so 
P(R, then B) = 4/17 x 7/17 = 28/289

b)
P(R) = 4/17
no replacing, P(B) = 7/16
so 
P(R, then B) = 4/17 x 6/17 = 24/289

c)
The answers to parts a and b are not the same. 
Part a (28/289)  with replacing, the probability to select a red then blue is higher then part b (24/289)

The probability that a plant is edible is 4/5 and the probability that a plant grows at a constant rate and is edible is 14/19.
miskamm [114]

Answer: Probability that a plant grows at a constant rate, given it is edible is given by \frac{35}{38}.

Step-by-step explanation:

Let B be an event that getting a plant grows at a constant rate.

Since we have given that

The probability that a plant is edible is given by

P(A)=\frac{4}{5}

The probability that a plant grows at a constant rate and is edible is given by

P(A\cap B)=\frac{14}{19}

We will use "Conditional probability ", i.e.

P(A\mid B)=\frac{P(A\cap B)}{P(A)}

P(A\mid B)=\frac{\frac{14}{19}}{\frac{4}{5}}\\\\P(A\mid B)=\frac{14\times 5}{19\times 4}\\\\P(A\mid B)=\frac{70}{76}\\\\P(A\mid B)=\frac{35}{38}

Hence, Probability that a plant grows at a constant rate, given it is edible is given by \frac{35}{38}.
